PPK: Unable to connect to the ppk, check debugger connection and make sure pynrfjprog is up to date

I'm trying to use the PPK with an nRF51 dev board, and I'm getting this output whenever I try to start the PPK Software:

Checking installed packages
pyside:		 1.2.4
pyqtgraph:	 0.10.0

pynrfjprog:	 9.0.0

Power Profiler Kit started, initializing...
Unable to connect to the PPK, check debugger connection and make sure pynrfjprog is up to date.

As far as I can tell, I have the PPK connected correctly. The PPK is on the NRF51 dev board, USB is connected to the NRF51 dev board, Power Select on the PPK is set to "DK", but the application won't start.

All switches are in 'DK' position as described here?

You are sure the PPK is correctly mounted on the DK (all pins align)?

You can check if you have connection to the PPK chip through the debugger by for example running the command nrfjprog -r -f nrf52. Make sure that SB9 is cut on the DK so that the chip you 'see' is not the one on the DK.

If the wrong firmware is running on the PPK chip (if you accidentally programmed it instead of the DK), you can reprogram the firmware by running the flash_ppk.py script inside the software folder.
